| error[E0382]: use of moved value: `a` |
| --> $DIR/custom_mut.rs:12:20 |
| | |
| LL | let a = CustomMut(&mut ()); |
| | - move occurs because `a` has type `CustomMut<'_, ()>`, which does not implement the `Copy` trait |
| LL | let _ = method(a); |
| | - value moved here |
| LL | let _ = method(a); |
| | ^ value used here after move |
| | |
| note: consider changing this parameter type in function `method` to borrow instead if owning the value isn't necessary |
| --> $DIR/custom_mut.rs:7:14 |
| | |
| LL | fn method(a: CustomMut<'_, ()>) {} |
| | ------ ^^^^^^^^^^^^^^^^^ this parameter takes ownership of the value |
| | | |
| | in this function |
| note: if `CustomMut<'_, ()>` implemented `Clone`, you could clone the value |
| --> $DIR/custom_mut.rs:4:1 |
| | |
| LL | struct CustomMut<'a, T>(&'a mut T); |
| | ^^^^^^^^^^^^^^^^^^^^^^^ consider implementing `Clone` for this type |
| ... |
| LL | let _ = method(a); |
| | - you could clone this value |
